1. Locate studs in the vicinity with a stud finder and mark the center of the studs using a long level and carpenter's pencil (figure A).

2. If the ceiling is angled, use a sliding T-bevel to measure the angle and transfer that to your 2x4s (figure B). Put on safety glasses and dust mask and use the circular saw to cut the 2x4.

3. If one 2x4 isn't long enough, clamp a second 2x4 to the first and hold them in place (figure C). Use the T-bevel to mark the end of the second board so you can cut it to fit flush to the ceiling. Attach the two boards permanently with screws and remove the clamps.

4. Use the first runner as a template to cut your second one. Attach on either side of the ventilation duct using screws (figure D). Pre-drill holes for screws and make sure you're attaching the assembly to studs.

5. Cut more 2x4s to build a frame around the ducts (figure E).

6. Make templates for cutting the drywall pieces by pressing old wrapping paper against the frame. Score the drywall with a utility knife and cut the pieces to fit.

7. Attach the side piece of drywall to the frame using screws. Insert screws about every four inches around the perimeter of the drywall piece (figure F).

8. Before attaching the drywall sheet across the bottom, mark the position of the 2x4 cross braces on the wall and on the new drywall. Have a friend hold the piece in position while you attach it with screws. Make sure to drive screws into the cross braces.

9. Prime and paint the drywall.
